Disable UIPageViewController bounce

Question

Searched a lot for this one, but couldn\'t find a proper solution yet.

Is it possible to disable the bounce effect of a UIPageViewController and still

Answer 1

Edit: Do not use this solution. I learned afterwards that this introduces a bug where about 5% of the time, the user can't page in the same direction. They have to page back, then forward again to continue.

If you're using a UIPageViewControllerDataSource, a relatively simple workaround (and a bit hacky) is to disable bouncing each time the pageViewController:viewControllerBeforeViewController: delegate method is called. Here is an example implementation:

@interface YourDataSourceObject ()
@property (strong, nonatomic) UIScrollView *scrollView;
@end

@implementation
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController {
    if (!self.scrollView) {
        for (UIView *view in pageViewController.view.subviews) {
            if ([view isKindOfClass:[UIScrollView class]]) {
                self.scrollView = (UIScrollView *)view;
            }
        }
    }
    self.scrollView.bounces = NO;

    // Your other logic to return the correct view controller. 
}
@end
